IMAP to IMAP Email Migration Tool - 2026 Pricing, Features, Reviews & Alternatives

Your old mailbox holds ten years of invoices and contracts, and the provider has just set a closing date. You need an IMAP migration tool, because forwarding rules only catch new mail and dragging folders between two mail apps stalls halfway with no record of what made it. IMAP to IMAP Email Migration Tool signs in to both accounts on Windows and copies the old folders into the new one, keeping each message's original date, flags and read status.

The work happens on your computer. Mail goes from the old server through your PC to the new server. This IMAP migration tool keeps no copy on any SoftOrbits storage along the way. Microsoft accounts are opened on Microsoft's own sign-in page, so the program never sees that password. Gmail, Yahoo and iCloud take an app password that you can revoke once the move is done. Passwords are not saved, and after a restart you type them again.

📌 Typical situations

- A hosting company is retiring its mail service. You connect the old server under Other IMAP server, enter host, port and encryption, and copy everything while the old login still works.

- A small office has bought Microsoft 365. Each person's mailbox moves separately, after hours or at lunch, and if the tenant asks for admin consent on first sign-in, the program shows what to send to the administrator.

- Someone has a college Yahoo address and a newer Gmail account. The program folds the old mail into the newer box so only one inbox is left to check.

🚀 How to start

1. Install the program on a 64-bit Windows 10 or 11 PC.

2. Enter the source address on the left. A preset for Gmail, Outlook.com, Hotmail, Live, Yahoo, iCloud, me.com or mac.com is chosen from the domain.

3. Press Test and wait for Server responds, Sign-in and Folders to pass. A failed stage comes with a reason, such as IMAP being switched off in the mailbox settings.

4. Connect the destination on the right.

5. Review the folder map. Gmail's All Mail, Important and Starred start unticked because they repeat other labels, and Trash and Junk are unticked too.

6. Pick a period and press Start. Stop at any moment, the next run continues from that point.

🛡️ What keeps the copy clean

Before each upload the program checks the Message-ID in the destination and records every copied message in a local journal. We force-closed it 5 times in the middle of a transfer, and the destination ended with 2,160 messages, the same as the source. When a connection drops, it retries with pauses that grow from 2 to 30 seconds. Messages larger than the receiving server accepts are skipped and logged while the rest continue. That is the part people want from an email migration tool when the mailbox is large, and the reason an IMAP migration tool needs a journal at all.

👥 Who it is for

Office managers, freelance IT helpers looking for a dependable IMAP migration tool, consultants who set up mail for clients, and home users who need to migrate IMAP to IMAP once and get it right.

❓ FAQ

Is there a free email migration tool? Free options exist, mostly command-line scripts or the admin consoles of mail services. This program has a free trial that runs on your own mailbox.

How do I find my IMAP password for my email? Gmail and Yahoo issue an app password in the account security settings, and Google shows it only after 2-Step Verification is on. iCloud requires two-factor authentication first. Microsoft accounts need no app password.

How do I fix my IMAP problem? Make sure IMAP is enabled in the web settings, use an app password where the service asks for one, and match the port to the encryption. Port 993 usually goes with SSL/TLS and 143 with STARTTLS.
